In probability sampling, every individual in the population have equal chance of being selected as a subject for the research.
This method guarantees that the selection process is completely randomized and without bias.
In this type of population sampling, members of the population do not have equal chance of being selected.
Due to this, it is not safe to assume that the sample fully represents the target population.
This sampling method is usually employed in studies that are not interested in the parameters of the entire population.
Some researchers prefer this sampling technique because it is cheap, quick and easy.
The purpose of this paper is to describe sampling as a method of data collection, its methodology and types.
Background Household surveys are a key epidemiological, medical, and social research method.
Difficulties conducting surveys in these locations may explain this disparity.
We propose a generalisable, scientifically valid method that is sustainable and ensures community engagement.
